A coal washing machine is a complete set of equipment, mainly divided into jigging, flotation, heavy medium coal selection, dry coal selection, etc. And what we often refer to as equipment refers to jigs, which use the principle of different densities to layer coal seams with feng shui, discharge gangue and impurities, and recover clean coal that meets the requirements. So, how should this device be operated? Next, the coal washing machine equipment manufacturer - Shenzhou will explain to you, hoping to be helpful to you.

　　1. Startup sequence

　　First, turn on the water pump. When the water flows out of the washing equipment outlet, turn on the grading belt, dewatering screen, and lifting bucket (1, 2, 3) in front. Open the air valve again, then turn on the fan, (final coal screen), and feeding belt conveyor.

　　2. Lubrication

　　Apply butter to each oil hole of the air valve once per shift, and apply butter to the head of the hoist and vibration motor once a month. The first oil change time for each gearbox and fan is one month, the second time is every three months; From now on, change the oil every six months. When injecting oil, pay attention to the display of the oil gauge and oil window to avoid adding too much or too little.

　　3. Adjustment

　　Adjust each coal slurry valve (air valve) and shut-off valve (water valve) according to the coal type and material quantity. The normal sequence is to observe the opening of the first air valve and water valve from the feeding port, and then decrease in sequence.

　　4. Shutdown sequence

　　Stop the feeding belt conveyor (final coal screen) first, then stop the water pump, fan, and air valve. Under normal circumstances, stop the conveyor when there is no material in the lifting bucket, dewatering classification screen, or belt conveyor to avoid accidents when restarting.

　　5. Cleaning the bed layer of ore washing equipment

　　Clean every 10 days to remove iron tools and debris from the bottom of the screen, ensuring that each ventilation hole has good ventilation function. Regularly check the bolts in various parts to see if there is any looseness, and if there is, tighten them

　　6. Manipulation

　　Depending on the type of coal, the number of discharge times for each gate of the ore washing equipment should be increased or decreased. If the gangue content exceeds 20%, if there is no material in the lifting bucket, it must be discharged. The principle is to discharge frequently and release less. The head of the lifting machine is equipped with a safety pin, which will not disconnect under normal circumstances. If the promotion amount is exceeded, it may disconnect. After reinstalling the safety pin, it is necessary to retest the machine and check for any jamming. If any, it should be eliminated before production can begin.

　　In summary, it is the operating skills of the coal washing machine. Seeing this, I believe you have also gained some understanding, and we can refer to the above skills to operate and avoid problems in the later stage.
